Today I learned

TIL

If you've got a shuffled (i.e. not brand new) deck of cairds in your hoose, the order they're in will be the first time in history a deck of cairds have ever been in that order.

The number of possible permutations a deck order can be in, is a bigger number than there are atoms on earth 🤯
It's all a deck of cards

If a deck of cards was shuffled every second since the start if the universe the same deck would not be repeated, in fact it would barely make inroads into the number of possible permutations.

I caught sight of this due to a youtube video, where it played this out in terms of walking round the earth but taking a billion years between each step and still not touching the sides after so many times round the planet.. its a truly, truly mind boggling number.

Exponential growth (and degrowth) is quite shocking.

Another old fave is the chess board with a grain of rice on the first square, two on the next, four on the third square and keep doubling like that. The last square would contain 9 quintillion grains, which would weigh 1.4 trillion tonnes and be enough to cover India in a meter thick layer.

It had better be a strong chessboard!

It's double that 😳
 
Assuming PI is a truly normal but irrational number - such are the hazards of working in IT I was once waylaid for half an hour by some gimp questioning whether this is knowable - and the numbers after the decimal point don't ever settle into a repeating pattern:

It contains every text ever written, numerically encoded. The Bible, works of Shakespeare, Daniele Steele...
 
I Just found out that Graham's number is the biggest of them all.
I just googled that and it isn't, I mean there can't be - you can always +1!

But its big enough that it couldn't be written down inside the universe as it would exceed available atoms. But bizarrely it's last several digits are apparenty known!
 
To be fair, when my 6yo asks me what the biggest number is I always tell him it's a Googolplex!
If there is one thing I am glad to not be very good at its maths. I think the real maths geniuses are liable to be driven mad by it and even your more regular whizzes can often be a bit odd.

No wonder. Some of these tidbits we are trading just melt my heid. I would hate to have to spend my time thinking about them!

I would imagine that's the biggest with a name.

I wonder what the ofds are for der hun to have a run of 18 home games, and counting, in cup competitions
 
I remember thinking "ya dafty" when Cat Stevens turned Muslim but hey ho 🤷
I've just seen an old clip of him on some panel discussion where he supported the calls for Salman Rushdie's death. When pushed he also said if ordered to he would carry out the act himself.
Peace loving hippy to someone willing to kill an author for writing a book. *&*^!

Yup. I remember that. Also remember 10,000 Maniacs removing their cover of his songs Peace Train from their album in protest. The response to the fawa on Rushdie was cowardly and shameful. Leader of a country publically issuing a death warrant against someone for writing a book. A line should have been drawn in the sand at that point. Of course it wasn't. Message that Western democracies will do fuck all when their citizens are threatened by religious nutters.

Exactly. I also saw today that Rushdie was stabbed 14 times on stage. He was lucky to survive.

what should they have done Sancho?
 
Given that Earth's diameter is less than 8000 miles at the (fat) Equatorial bulge and the Moon is around 238,000 miles away I'm not sure why you're surprised 🤔

Earths diameter doesn't come into it though 🤓

The moons just VERY far away.
Wouldn't think it looking outside tonight though.
